Util.Delayer
Description
Delayers handle delaying of actions; the main purpose is to delay graph redrawing actions during complex updates.

carry out the given action preventing the Delayer from doing anything.

cancelDelayedAct :: Delayer -> DelayedAction -> IO () Source #
If this DelayedAction is queued, remove it from the queue.
class HasAddDelayer eventSource where Source #
Instances of HasAddDelayer are event sources to which you can attach a delayer, to indicate you are currently not interested in events.
Methods
addDelayer :: Delayer -> eventSource -> eventSource Source #
Instances
| HasAddDelayer (VariableList a) Source # | |
Defined in Util.VariableList Methods addDelayer :: Delayer -> VariableList a -> VariableList a Source # | |
class HasAddDelayerIO eventSource where Source #
Like HasAddDelayer, but allows an IO action.
